The RRC has issued one drilling permit, issued March 14, 2018, permitted to 7,550 ft.
It was permitted by Xto Energy Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Its lease has reported 76.9M barrels of oil and 65.2M mcf of gas since January 1993, last reporting in July 2026. The lease carries 1,406 wells, so these are lease totals, not this well alone.
